I had a previous entry on doing a Laguna historic route which is a big loop around the historic and interesting tourist towns in Laguna. This is about the smaller loop within Kaliraya Lake (Lumban, Kaliraya, Cavinti and Pagsanjan). This is ideal as a side activity when you are staying in one of the popular resorts along Caliraya Lake. Since Caliraya is located in a higher elevation- there will be challenging climbs from Lumban to Caliraya. Total distance of the loop is around 45-50 Kms.
There are a couple of affordable resorts (even through airbnb) along the lake so a perfect biker’s long weekend is to spend a day in one of the resorts and have a short ride early in the morning.
